IMPROVEMENT IN PRESSES.

The Schedule referredt Ln these'LetterePatent and. making part of the same..

To all whom it may oozwern:

Be it known that I, ISAAC H. TRABUE, of the county of Livingston, in the State of Kentucky, have Corresponding letters refer to corresponding -partsV in the two figures. l

The nature of -my invention lconsists in combining and arranging, in av press for pressing hay, cotton, tobacco, Sac., a series of xed, audaseries of movable pulleys, to obtain the necessary power, as hereinafter more fully described. p

To enable those skilled in the art to make and use my invention, I will proceed to'deseribe its construc-v tion and operation.

A, in the drawings, -represents the platform of a press, on which the frame B is mounted, which, if to be used for pressing and baling hay, cotton, and like substances, may be constructed as shown, or in any substantial manner which may be best adapted to the purpose for'which it is to be use'd.

.C is the base or lower platen.

D, hinged doors.

E, the feed-box and guide for the plunger.

This brief reference to these several parts' will be sufficient to 'au understanding ot' the case'as their construction andai-rangement are similar' to that in presses for like 'purposes nowv in common use.

F represents a stout Across-beam, which is iirmly secured to the sides of the flame, about. midway bet'ween the base and the, upper cross-beam. ln the centre Ait is provided with a mortise or square hole through which the plunger-rod passes. 0u each side of this it has vertical slots. ln this case I have shown three on one side and -two on the other, for the reception of pulleys or sheaves.

G represents the iixed pulleys, which are. to be placed on horizontal shafts in the slots of the crossbeam F, in such a manner that 'their peripheries are about flush with the under surface thereof.

H represents the plunger, which works freelyv up and down between the sides of the frame'and feedborr.- Its rod H1 passing through the cross-beam F, has at its extreme end a boss, H2, provided with slots, the number of which is determined bythe number of pulleys to be used.

-I represents the movable pulleys, which are placed on a shaft in the slots of the boss of the plunger-rod, their number being, equal to the number of fixed pulleys;

K represents a strong rope, one end of which is fastened to the cross-beam F, then passed over one of the movable pulleys I, and downward over one of the fixed pulleys H, then returned, and so on, till enough pulleys have been brought into. play to give the required' force, when a given force is applied at the loose end ofthe rope'. The rope is then passed over the pulley Kl'in the side, ofthe frame, and thence down'- ward over the pulley K2, which is secured in any suitable manner either to the frame 4orgto the platform.

L represents another rope, bywhieh the plunger is to be raised. To this end it is secured on top of the plunger-rod, and passed through afhole in the upper cross-beam of the frame over the pulleys Ll and L2, which are to be placed in the frame, and thence downward over the pulley L, which is secured by the side of the pulley K.

M and M represent ropes, which reeve over pulleys lm. and m in the sides of the frame. One end of each of these ropes has a loop, which is to embrace the rope K, and the Aother end is to be weighted.

The operation is as follows:

The several parts having been arranged as described, the'plunger is raised to its highest position by applying the necessary force at the loose end of the rope L. The box is then filled with the substance to be pressed, when the plunger is allowed to descend by releasing the end of rope L, coming downwith considerable force, and somewhat compressing the substance. The Weighted looped ropes M and M will prevent the rope K from becoming' entangled. The plunger is again raised, and the operation repeated` until the box is full, when power is applied at the loose" end of the rope K suiiicient toproperly compress the substance, when itmay be.bound, and taken 4out of the press.

Having thus described my invention,

That I claim, and desire to secure by Letters Pat ent, is'

The combination and arrangement, in the press herein shown, of the fixed pulleys G, rope K, movable pnl? leys I, plunger H, and rope L, substantially as shown and described. I

ISAAC H. TRABUE.
